--- Comment #4 from Alexander Popov <alex.popov at linux dot com> ---
> Incorrect.  There is also a zero_call_used_regs attribute.

Thanks, now I've found it in your tree:

```
You can control this behavior for a specific function by using the function
attribute @code{zero_call_used_regs}.
```

Could you explain the connection between your attribute for zeroing registe=
rs
and 'no_caller_saved_registers' attribute?=
